It uses OEM part numbers HB5R1 and HB5R1H. The cell matches original voltage and capacity so the phone's charge IC operates within spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG500 series compatibility:\u003c\/strong\u003e\n    The U8832, U8832D, U8520, and G500D share the same battery bay dimensions, connector pinout, and BMS communication protocol. All run the same 3.7V nominal rail, so one cell covers the full group without voltage or connector conflicts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the G500 platform. The BMS handshake completed cleanly, charge IC accepted the cell on the first cycle, and the fuel gauge IC reported state-of-charge without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle before returning to normal settings. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging begins on an uncalibrated cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the G500 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Ascend G500 uses a fuel gauge IC that builds its state-of-charge model from the cell it was calibrated against. Swap in a new cell and the IC is still referencing the old cell's discharge curve. The percentage shown on screen reflects that stale model, not the new cell's actual charge level. One full discharge down to auto-shutoff followed by an uninterrupted charge to 100% forces the IC to rebuild its model against the replacement cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet recalibrated and the reported percentage sits well above the cell's actual voltage under load. When the modem transmits or the screen peaks in brightness, current draw spikes and the cell voltage drops sharply below 3.2V — the BMS trips and the phone cuts off. The screen shows 25% right up until shutdown because the IC is reading from the wrong model. Run one full discharge-charge cycle and the reported percentage will track actual cell voltage accurately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405009289306,"sku":"BWCS-HU8832SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405009322074,"sku":"BWCS-HU8832SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405009354842,"sku":"BWCS-HU8832SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HU8832SL-1.webp?v=1779369806","url":"https:\/\/batteryweb.com\/products\/huawei-u8832-replacement-battery-37v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
